TNSO'LE-TOE-LIP-MOLDING MACHINE.

Application filed August 6, 1921. Serial No. 490,237.

To all whom it may concern:

Be it known that I, LLoY E. WHELPLEY, a citizen of the United States, and resident of Beverly, county of Essex, State of Massachusetts, have invented an Improvement in Insole-Toe-Lip-Holding Machines, of which the following description, in connection with i the accompanying drawing, .is a specificas tion, like characters on the drawing representing like parts.

This invention relates to machines .for molding insoles, and particularly to a ma chine constructed to mould the toe'portion of the in-seam-receiving rib of an insole.

While the machine'can be used on any insole having an inseam-receiving rib, it is Y specially useful in connection witli'the type of insole having a body layer, of leather or similar material, that is channelled to provide arlip, and a layer of canvas or duck which is adhesively united to saidbody layer and overlies and reinforces the inner face at least of said lip. I

In the manufacture of these insoles, some difiiculty is frequently experienced in pressing the duck or canvas layer firmlv. against the lip at the toe portion of the shoe, especially where the insole has a very pointed toe.

My invention provides a machine adapted to operate on the toeof an insole and arranged to firmly press the canvas layer against the inner face of the upturned. lip at the toe portion, and also arranged to mould or shape this lip at the toe portion, so that it will have the correct contour.

In order to give anunderstanding of my invention, I have illustrated'in the drawings a selected embodiment thereof, which'will now be described, after which the novel features will be pointed out in the appended claims. 1

Fig. '1' of the drawings is a side view of a machine embodying my invention.

Fig. 2 is a plan View of the molding elements, showing the manner in which they operate on the insole. 7

Fig.3 is; a section on the line 33, Fig. 2.

Fig. 4 is a perspective view of the toe portion of an insole, showing the manner in which one of the mould members operates thereon. 1 r p i The machine herein illustrated is provided with a base or bed 1, on which the insole 2 1s supported, and it is also provided with two mould members adapted to engage, the outside and inside of the toe portion of the inseam-receiving rib, and press or mould said portion into the desired shape.

The insole 2 is of the familiar type having the upturned in-seam-receiving rib 3, and the feather edge 4 exterior to the rib. The insole shown in Fig. 4: is of the type having a reinforcing layer 5 of canvas or duck which is cemented to the body portion of the insole, andwhich overlies the inner face of the inseam-receiving rib.

As stated above, difficulty is frequently experienced in properly pressing together the fabric layer and the upturned lip of the insole body atfthe toeportion of the insole,

especially where the'insole has a'very pointed toe, as shown in the drawings. The-mould members which are designed to accomplish this are herein indicated at 6 and .7 respectively. The mould member 6 is detachably secured to the bed 1 by means 'of suitable clamping screws 8, and it is provided with a reentrant portion 9 of a shape to fit the outside face of the toe portion of the inseam-receiving rib 3. Said mould is also provided on its under face with a recess 10 of the'proper dimensions to receive the feather edge a of the insole, so that when the insole is placed on the be'd, the feather edge at the toe portion may be inserted into the recess 10, and the rib 3 fitted intothe reentrant portion 9. I

, The mould member 7 is of the proper shape tofit the inner face of the rib 3 at the toe portion, and the machine is so constructed that when it is operated, the. mould member 7 will be brought against the face of the insole, as shown inFig. 4:, and will then be movedwforwar'dly into the angle 11 formed by the toe .portion of the inseam-receiving rib, thereby to mould saidtoe portion be tween itself and the reentrant-portion 9 of the same'time pressed againstthe insole, so

that the fabric layer 5 will be firmly pressed against the body of the insole at the toe portion.

One of'the mould members is preferably heated so that the molding operation will be accomplished by both heat and'p'ressure,

L st) and I have herein shown the mould member 7 as heated.

Any suitable means may be employed for actuating the mould member 7. it is herein shown as provided with ears 12, which are pivotally connected to a member 13, as shown at 14. This member 13 is provided with a slot 15, which is received in the forked end of an upright 16, that rises from the bed 1, said upright having a pin 17 extending through the slot.

The link 18 is pivotally connected to the member 13 at 19, and also pivotally connected at 20 to an arm 21, which in turn is pivoted to the bed at 22. This arm 21 is connected by a link 23 to a treadle 24. The arm 21 is acted upon by a return spring 25, one end of which is connected to the treadle 23 and the other end of which is connected to the bench 30 on which the machine is supported, as shown at 26. When the treadle 24 is free, the spring 25 will raise the arm 21 into the dotted line position, and said arm acting through the link 18, will raise the 'member 13 and mould the member 7 into the dotted line position. When in this position, said mould member is elevated above the bed, so that the latter is free to receive the insole to be moulded. After an insole has been placed on the bed in the position shown in Figs. 1 and 2, the pressure is applied to the treadle, thereby moving it into the full line position Fig. 1. This operates through the link 23, arm 21 and link 18, to bring the mould member 7 against the insole with a downward pressure, and also operates to move the mould member 7 into the reentrant portion 9 of the mould member 6, with the result that the toe portion of the in-seam-reeeiving rib 3 will be moulded into the desired shape between said mould members. To produce a sufiicient downward pressure of the mould member 7 against the insole, I provide the member '13 with a roll 28, adapted to pass under a flange or arm 29 extending from the upright 16 as said member 13 is moved into the full line position. This arm 29 and roll 28 cooperate with the link 18 to give the mould member 7 not only a forward movement into the reentrant portion 9, but also a downward movement against the insole.

The mould member 7 is heated, and this is accomplished by providing the member 13 with an electrical heating unit indicated at said heating unit operating to heat the member 18, and also to heat sulficiently the member 7.

The operation of molding aninsole inolves simply the placing of the insole into the machine, and then the depressing of the treadle 241-.

The heating of the mould member 7 is antageous because the heat softens the .ntitious substance by which the duck layer is attached to the insole thus per mitting the duck to be crowded firmly into the corner of the rib at the toe portion.

In the manufacture of shoes it is highly advantageous to have the toe portion of the rib 8 correctly formed because when the rib is properly shaped at the toe portion it 'is possible to last the toe of the shoe more evenly and also to stitch the shoe better than if the rib is imperfectly formed.

I will preferably make the arm 29 slightly resilient so that it will give sufficiently to accommodate insoles of different thickness.
